FreeRTOS Theory and Practice

Description

The concepts and commands necessary to make effective use of FreeRTOS are described through a combination of theory and on-the-job training. Learn from an experienced trainer and take away a working knowledge of FreeRTOS and the ability to use it effectively in your own embedded projects.

Objectives Overview

Online or On-site Options

On-site training can also be provided when the number of trainees is high enough. The point at which on-site training becomes cost effective depends on the geographic location.

Course Details
Title	FreeRTOS in Theory and Practice
Delivery	The course is normally presented online with instructor screen sharing. On-site training can also be provided where attendee numbers make this cost effective.
Duration	Modular, up to three days
Language	Course material is provided in English. Instruction can be provided in either English or German.
Who Should Attend?	People with an interest in, or who have been tasked with, development of a resource constrained real-time system. For example, embedded software engineers, field application engineers, project managers, etc.
Course Material and Equipment	The following items are provided: A bound course book, priced extra per copy Low cost target hardware, typically an LPC1769 LPCXpresso Board, priced extra per board A CD containing the examples and solutions Please note, we do not permit re-use of our copyright material.
Prerequisites	Attendees should have: A basic familiarity with using a Windows system as an end user Familiarity with embedded C concepts and programming The ability to develop software using the C language The ability to use an embedded compiler and embedded debugging tools Basic knowledge of embedded microcontroller development boards
Pricing	Private online sessions cost €3700 EUR for the full three days (approximately $4560 USD), offering excellent per person per day value for larger groups. The same course can be delivered on-site for the addition of the travel and living expenses incurred. Please use the form below to make an enquiry. Public online sessions cost €1250 EUR (approximately $1600 USD) and are provided as and when enough people have registered an interest in a single time zone band.
